REFUSE- BURNER.

SPECIFICATION forming part of Letters Patent No. 371,203, dated October 11, 18E7.

Application filed March 8, 1887.

To all whom it may concern.-

Be it known that I, WILLIAM MANN, of the city of Montreal, in the district of Montreal, Province of Quebec, Canada, have invented new and usefulImprovementsin Refuse-Burners; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to the construction and arrangement of a furnace for the purpose of cremating the vegetable, animal. or other combustible matter collected in cleaning the streets, &c., of cities, towns, villages, &c., or in the general scavenging of such, to produce a furnace in which such combustible refuse may be consumed in a'more inexpensive and less laborious manner, and with a less amount of noxious vapors or gasesbeing given off to create disease than in the furnaces at present in use for this purpose.

, In the drawings hereunto annexed similar letters of reference indicate like parts.

Figure 1 is a side elevation ofa crematingfurnace embodying my invention. Fig. 2isa front end elevation of the furnace shown in Fig. 1. Fig. 3 is a longitudinal vertical sec tion of the said furnace, taken on lines 00, Figs. 2 and 4. Fig. 4 is a transverse vertical section taken at line 00, Fig. 1. Fig. 5 is atransverse vertical section taken at line 1 Fig. 1.

Letters a are furnaces. As shown,tl1ese are four in number; but a greater or less number may be used, as desired. The furnaces a are provided with feed openings 7), fire-bars c, and ash-pits d, having openings 6 and f. All the openings, 1), e, and f, are provided with ordinary doors, g, h, and i, by which the said openings may be closed when desired. The topslc 7c of the furnaces are preferably so arranged that two furnaces are embraced under one arch, k, to give a greater spread to the flames;

lis a chamber so arranged with regard to the furnaces a that the furnaces a occupy the lower part at one end, thus forming aspace, a, above the furnaces. The chamberlis provided with fire-bars m, ash-pits n, openings 0, p, and 1, each provided with ordinary doors, r or s,- also with opening of flue t to chimney 1;.

Serial No. 230,095. (No model.)

The operation of the invention is as follows: Strong coalfires are formed in the furnaces a, and after the chamberl has been sufficiently heated the material to be cremated is passed into the chamber by the openings 0, and by rakes introduced through the opeuingsp distributed upon the fire-bars m; also, the ashes accumulating on the bars at may be raked down through the bars into the ash-pits n, from which the ashes will be removed by the openings q.

Attention is called to the position of the arches or tops k of the furnaces a as being an important feature in this invention, because by forming a space, a, above them an eddy is caused, as indicated by the arrow in Fig. 3, by which the gases arising from the material being cremated are brought over and over again to be acted upon by theintense heat at the back end of the furnaces a, and thus are more perfectly consumed before passing by the opening or fine t to the chimney.

A number of chambers,l, provided with furnaces a,and otherwise constructed as above de scribed, may be arranged and connected with one chimney, n, or each chamberl may be provided with a chimney in any ordinary manner; but in any case a liberal amount of chimneypower to form a very active draft should be provided.

What I claim, and wish to secure by Letters Patent, is as follows:

The combination, in a refuse-burner, of the furnace a, consisting of a suitable casing having suitable inlet and outlet openings, 0,1), and c, the grate-bars m and ash-pit a. the chamber tops or arches k, and flue t, the whole constructed, arranged, and operating together, substantially as described, for the purposes set forth.
